Paranormal Investigators use many of the techniques and equipments for Spirit Communications. But now a days, they are using a device which is a Spirit Box.

A Spirit Box is an audio-only device that rapidly scans through multiple audio channels that is said to make it relatively easy for ghosts to manipulate to say a word or phrase in real time. It has been proven that sounds other than spoken language can be captured on the spirit box and is usually discovered as something other than what is surrounding the investigator.

A Spirit Box uses white noise as a medium to communicate with spirits. white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density.

So my pondering is this; What does it take for a spirit or ghost to move an object or knock on a wall?

If a ghost/spirit is energy, then doesn't that mean that we should be able to find them using certain levels of technology?

EMF Spikes, are they valid? The body emits a constant electric field, some call it the aura and others claim to see and controll theirs, there are the pictures of Vridian (SP?) cameras that have the aura of plants and such.

So are we barking up the right path to see ghosts? Couldn't the same kind of image caputring technology be used to find our wandering spirits?What happens to a spirit when they pass on? Does the energy dissapate into something else or get transfered to another plane of existence or another dimension perhaps?

Why is everything always a cold spot? Is a cold spot us finding a ghost/spirit? Is a cold spot just a door way? Doorway to what? You tell me.
